Under the terms of the Agreement, on November 27, 2017, directors Steven W. King, Carlton M. Johnson, Jr., Eric S. Swartz and David H. Pohl each tendered his resignation, effective immediately, from Peregrine's board of directors, and from the board of directors of its wholly-owned subsidiary, Avid Bioservices, Inc. The vacancies created by these resignations were immediately filled by three individuals who were nominated by Ronin/SWIM for election at Peregrine's upcoming 2017 Annual Meeting of Stockholders (Richard B. Hancock, Gregory P. Sargen and Joel McComb), and one director (Joseph Carleone, Ph.D.) who is independent of Ronin/SWIM and new to Peregrine. Roger J. Lias, Ph.D., Mark R. Bamforth and Patrick D. Walsh, the remaining members of Peregrine's and Avid's original boards, will continue to serve in their respective roles with the company.

"We are pleased to have reached an agreement with Ronin/SWIM and believe that the addition of Messrs. Carleone, Hancock, McComb and Sargen, each with significant experience in the biomanufacturing industry, will add great value as we work to establish Avid as a leading contract development and manufacturing organization," stated Roger J. Lias, Ph.D., President of Avid Bioservices.

Stephen
White of Ronin/SWIM said, "We are pleased that we were able to reach a constructive agreement with Peregrine to reconstitute the board with new independent directors. Rick, Greg, Joel and Joe bring important experience, expertise and perspectives to Peregrine, and we are confident that they, together with Roger, Mark and Pat, will be able to successfully lead the company forward and deliver value for stockholders."

As part of the Agreement, Ronin/SWIM, which collectively beneficially owns 9.6% of Peregrine's outstanding shares of common stock, withdrew its nomination of six candidates for election to Peregrine's board of directors at the upcoming 2017 Annual Meeting of Stockholders and has agreed to certain standstill restrictions until the date that is thirty calendar days after the 2018 Annual Meeting of Stockholders. Peregrine has also agreed to
re-nominate a number of Ronin/SWIM's appointees at the 2018 Annual Meeting of Stockholders.

The complete Agreement will be included as an exhibit to the company's current report on Form 8-K, which will be filed with the Securities and Exchange Commission.
